Autumn has officially begun, but summery weather is set to continue this weekend with mainly warm and sunny days across the country.
Today sunny spells will break through morning cloud delivering a beautiful day to most of the North Island and temperatures in the mid-20s.
There are chances of patchy drizzle around the East Cape and Northland.
A front moving up the South Island will bring rain in the west and south, but this will weaken and turn to scattered showers and cloud as it moves north.
Cantabrians are in for a scorcher of a day with temperatures expected to reach 28C.
The front will also boost temperatures in Hawke's Bay over the weekend where some areas will reach 30C, Napier will also hit 28C and Hastings 29C.
The weather will also be hot and mostly fine in Northland, Gisborne and the Bay of Plenty on Saturday.
And with the sun set to come out to play this weekend it is the perfect time to throw on your togs and go to the beach. Niwa said sea temperatures have warmed dramatically to between 20C and 22C around the upper North Island.
It's also good news for cricket and coffee fans in Auckland as the Black Caps take on South Africa at Eden Park and the finest lattes are up for sampling at the Coffee Festival on Saturday, when showers promise to hold off until the evening.
On the flip side, Taranaki and Wanganui may see a few showers tomorrow morning.
Sunday is mostly sunny again, apart from on and off cloud in the west of both islands.
